PNEUMATIC LINT CLEARER FOR WARPING MACHINES.

Application filed Dec'ember' T 0 all 'wlmm it may concern:

Be it known that we, FRANK B. KnNNnY and JOHN lV. Sunum'rrmu, citizens of the United States. residing at Lowell, in the county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in Pneumatic Lint (lea-rers for \Varping Machines, of which the following is a specification; reference being had therein to the accompanying drawings.

Our invention is applicable to warpingmachines, looms, and the like. and has relation to the class of devices or appliances which have been devised for employmentin such machines to effect the removal of the lint that separates from the yarns or threads that are operated upon therein.

The invention is, more especially, an improvement upon the pneumatic lint-clearer that is shown and described in former Lctters Patent No. 1,339,182, granted under date of May 4, 1920.

The invention consists in a novel and improved lint-clearer designed for use in connection with warping-machines, looms, and other machines in which a sercs of traveling yarns or threads arranged side by side in the manner of a warp are operated upon, and comprising a traveling blower disposed above the yarns and having means to effect its oscillation in a uniform general direction to deliver a sweeping blast or current of air through the yarns, combs, guides, and dropwires for the purpose of clearing lint away from the same.

The drawings represent an illustrative embodiment of the invention in connection with a warping-machine.

In the drawings,-

Fig. 1 is a front elevation of the said warping-machine and illustrative embodiment.

Fig. 2 is a View in vertical section in the plane ofi the dotted lines 2-2 of Fig. 1.

Fig. 3 is a front view on a larger scale than Figs. 1 and 2, showing the famblower.

to which reference is made hereinafter, and the parts more immediately associated therewith.

Fig. 4 is a view of the parts which are represented in Fig. 3, looking from the lefthand side in the latter figure.

14, 1921. Serial No. 522,198.

The drawings represent a typical warpingmachine and the preferred arrangement, etc.-, of the lint-clearer in connection therewith.

In Fig. 2 yarns or threads 1 are represented as extending from a war .)er-creel (not shown) through the back comb 2, over the measuring roll 3.under the movable falling rod 4, over the supporting roll 5, through the front comb 6, over the front supporting roll 7, to the warper beam 8, on which latter they are wound by the action of the machine. Drop-wires 9, 9, are represented as hung in usual manner upon the yarns or threads at points between the rear supporting roll 5 and the front comb 6.

The lint-clearer is shown applied and arranged to operate to blow away lint which separates from the yarns or threads during their passage from rear to front at the top of the machine, and to keep the hack and front combs, drop-wires, and other parts adjacent the drop-wires, clear and free from lint.

In this embodiment of the invention suit.- able stands 10, 10, erected above the bed of the warping-machine, support a right and left traverse screw 11 of well-known character shown in Fig. 3. Said traverse screw revolves in bearing-sleeve 12, 12, fixed in the upper extremities 13, 13, of the stands 10, 10, and is rotated by means of bevelgears 14, 14', an upright shaft 15, and the worm and worm gear 16, 16', from the slowm'otion drive mechanism. Surrounding the traverse screw 11 is a sleeve 17, fixedly supported upon the upper ends of the arms 18. 18, of the stands 10, 10, and constituting a support and guide for the traversing collar 20 which surrounds said sleeve, and is adapted to slide along the same, the said sleeve having in its upper portion a longitudinal slot 17' in which works a pin '15) projecting inward and downward from collar 20 and provided at its inner end with a follower working in the grooves of the traverse screw. In obvious manner, the traverse screw through' its rotation operates to traverse the collar 20, and the parts which are carried thereby, back and forth across the machine, from one side of the latter to the other. With the said collar I connect a blower by means ofwhich a current of air is sent toward the yarns or threads and the various machine parts at the top of the machine. Through the traversing movement of this blower in unison with a collar 20 the said current of air is caused to take effect in the different portions of the width of the machine successively. In this instance, the blower is an electric fan 24, which is preferred, although the inventi'on is not necessarily restricted in all instances to the use of a fan-blower. The said fan 24 is shown mounted between the arms of abail or yoke 22, having at the top thereof a neck or boss which issocketed to fit upon-a pin or stud 21 carried by and projecting downward from the collar 20, the bail or yoke being fixedly attached to the stud or pin by means of the clamping-screw 23.

To provide for the oscillation of the blower, the fan 24, which affords a convenient means of producing the necessary current of air, and is adopted for such purpose in the present embodiment, is suspended between the arms of the bail or yoke 22 with capacity to swing in a vertical plane about a horizontal axis. Provision for such swinging motion is made by providing journals 25, 25, on the fan caslng and mounting them to turn in bearings in connection with the arms. In this instance, well-known devices are shown for oscillating the fan on its journals automatically, such devices comprising a jackshaft 26, gear-driven by the main fan-shaft and extending outwardly from the fan-casing and having fixed on its outer end the disc or plate 27, and a link 29 coupled at one of its ends to a crank-pin 28 borne by the disc 27 and at its other end to a pivot-pin 30 formed upon a suitable member fixed upon the bail or yoke 22, such as an L-headed pin 31 having the attaching portion thereof driven into a hole provided for it in one arm of the bail or yoke. When the fan rotates, the jackshaft 26 rotates also, moving the crank-pin 28 in a circular path with respect to said jackshaft. As the link 29 is pivoted at one end to a member that is fixed with respect to the bail 22, and cannot move in the direction of its length, the travel of the crank-pin 28 to which the other end of said link is attached serves to turn the fan back and forth upon its journals 25, 25, and thus to end of the machine. The plunger 33 thereof is arranged to be depressed by a finger 34 upon the pedal rockshaft 35 to close the switch and let the current flow only when the warping-machine is running on high speed.

With the switch arranged to be actuated from the pedal shaft as just described, the blower is automatically setin action and commences to oscillate as soon as the warping-machine is put on high speed. At the same time, it is traversed across the width of the machine, so that the current of air is directed progressively to the whole width of the yarns. i

In the drawings, the axis of oscillation is disposed crosswise of the machine, and consequently the plane of oscillation is foreand-aft, i. e., in the direction from front to rear parallel with the yarns or threads. This enables the current of air to act lengthwise of the yarns or threads as the blower oscillates, so that the air passes more directly and more readily down through the yarns or threads and acts advantageously in effectin the removal of lint from them and from t e machine parts adjacent the yarns or threads without a tendency to cause loose particles to lodge upon the latter. It will be obvious that this mode of operation is advantageous in the case of the application of the invention to a loom in connection with the closely-packed banks of drop-wires of the warp-stop-motion. It will be perceived on reference to Fig. 2 that the oscillation of the blower in a direction from front to rear will insure the action of the current of air substantially equally in connection with the back comb 2, the drop-wires 9, 9, of all the different banks thereof, and of the front comb 6, while the traverse of the blower across the machine will cause the current of air from the blower to take efi'ect equally in all portions of the width of the machine successively.

In case it should be desired to change the direction of oscillation of the blower, this may be accomplished by loosening the clamping-screw 23, turning the bail or yoke 22 around the pin or stud 21 of the collar 20 so as to effect the required extent of angular adjustment of the bail or yoke, and then tightening the screw 23.

It is contemplated substituting in some instances a nozzle for delivering air under pressure for the electric fan which is illustrated in the drawings.

What I claim is,-

1. The combination, with means for conducting a series of yarns or threads, of a blower carriagecom'bined with means for traversing the same from side to side across the series of yarns or threads, a blower connected with said carriage and traversing therewith, and means for oscillating the said blower in a uniform general direction during the traversing movements.

2. 'In warping machines and the like, in combination, a carriage, means for causing the same to traverse across the width of the series of warp-threads, a blower supported by said carriage, and means for oscillating said blower in the direction of the length of the warp-threads during the traverse.

3. In warping machines and the like, in combination, a carriage, means for traversing the same across the width of the series of warp-threads, a fan-blower pivotally hung in connection with the traversing carriage, and means connected with and operated by the fan-blower for oscillating the fan upon its pivotal mounting.

4. In warping machines and the like, in combination, a blower, a blower support on which the blower is pivotally mounted, means 'for oscillating the blower in a vertical plane, a carriage member with which said blower support is combined with capacity for adjustment around a vertical axis so as to cause the blower to oscillate iii the required direction, means for fixing the said blower support in a given position of angular adjustment, and means for traversing the carriage across the width of the warpthreads.

In testimony whereof we aflix 'our signatures, in presence of two witnesses.
